Generic ??-Riemannian submersions
(Hacettepe Univ, Fac Sci, 2022)As a generalization of semi-invariant xi(perpendicular to)-Riemannian submersions, we introduce the generic xi(perpendicular to)- Riemannian submersions. We focus on the generic xi(perpendicular to)-Riemannian submersions ... -
COVID-19 in elderly: Correlations of viral load, clinical course, laboratory parameters, among patients vaccinated with CoronaVac
(Akademiai Kiado Zrt, 2022)SARS-CoV-2 virus was initially identified in Wuhan, China, in December 2019 and a global pandemic was declared in March 2020 by World Health Organization. COVID-19 disease is characterized with severe pneumonia and hypoxemia, ... -
The Effects of the Covid-19 Pandemic on Distance Education in Higher Education: A Bibliometric Analysis Study
(Fac Teacher Education, 2022)This study aimed to examine the COVID-19 effect on distance education in higher education in the pre-COVID-19 pandemic (January to November 2019) and postCOVID-19 pandemic periods (December 2019 and January to December ... -
Alpha variant (B.1.1.7) of SARS-CoV-2 increases fatality-rate for patients under age of 70 years and hospitalization risk overall
(Akademiai Kiado Zrt, 2021)The emergence of new SARS-CoV-2 variants is a challenge to the control of this pandemic. It is therefore important to collect and to analyze data related to the infection caused by different variants. We have obtained more ... -
Geoid undulation prediction using ANNs (RBFNN and GRNN), multiple linear regression (MLR), and interpolation methods: A comparative study
(Univ Nacional De Colombia, 2021)This study evaluated different methods for geoid undulation prediction and included two types of artificial neural networks (ANNs) -the radial basis function neural network (RBFNN) and the generalized regression neural ... -
Culture-led Urban Transformation Strategies for Industrial Heritage and Industrial Areas in Istanbul
(Konya Technical Univ, Fac Architecture & Design, 2021)Purpose In relation to the advances in information economics the flow of capital, creative industries, highspeed transportation systems and spatial characteristics of cities have led to the proliferation of cultural ... -
Generalizations of ss-supplemented modules
(Vasyl Stefanyk Precarpathian Natl Univ, 2021)We introduce the concept of (strongly) ss-radical supplemented modules. We prove that if a submodule N of M is strongly ss-radical supplemented and Rad(M/ N) = M/ N, then M is strongly ss-radical supplemented. For a left ... -
Best proximity point theorems for cyclic p-contractions with some consequences and applications
(Vilnius Univ, Inst Mathematics & Informatics, 2021)In this paper, we introduce the concept of cyclic p-contraction pair for single-valued mappings. Then we present some best proximity point results for such mappings defined on proximally complete pair of subsets of a metric ... -
Phytochemical Screening, Antimicrobial, Antipellicle and Antibiofilm Activities of the Root of Alpine Medicinal Plant (Arnebia euchroma (Royle) IMJohnst.)
(Hard, 2024)This study aims to analyze the phytochemical and antimicrobial-related assays including antibacterial, antifungal, antipellicle, and antibiofilm potential of the root of an alpine medicinal plant (Arnebia euchroma (Royle) ... -
Analysis of the Thinking Process of Science Teachers: The Light Absorption Thought Experiment
(Univ Negeri Semarang, 2022)The aim of this research is to investigate the thinking processes of science teachers who are master students in science education regarding the thought experiment designed for the light absorption. For this aim, the ... -
Should We Postpone Elective Cardiovascular Procedures and Percutaneous Coronary Interventions During the COVID-19 Pandemic?
(Forum Multimedia Publishing, Llc, 2021)Background: Prioritization among patients with coronary artery disease represents a difficult issue during the SARS-CoV-2 pandemic. We present our clinical practices and patients' outcomes after elective, emergent and ... -
